Interaction ramps in a trapped Bose condensate
F. E. Zimmer, Masudul Haque
Non-adiabatic interaction ramps are considered for trapped Bose-Einstein condensates. The deviation from adiabaticity is characterized through the heating or residual energy produc…
Wave-function-based approach to quasiparticle bands: new insight into the electronic structure of c-ZnS
A. Stoyanova, L. Hozoi, P. Fulde +1
Ab initio wave-function-based methods are employed for the study of quasiparticle energy bands of zinc-blende ZnS, with focus on the Zn 3d "semicore" states. The relative energies…
Coherent manipulation of charge qubits in double quantum dots
Alexander Croy, Ulf Saalmann
The coherent time evolution of electrons in double quantum dots induced by fast bias-voltage switches is studied theoretically. As it was shown experimentally, such driven double q…
The three-dimensional gauge-glass model
Vincenzo Alba, Ettore Vicari
We investigate the temperature-disorder (T-S) phase diagram of a three-dimensional gauge glass model, which is a cubic-lattice nearest-neighbor XY model with quenched random phase…
Analytical calculation of fragmentation transitions in adaptive networks
Gesa A. Böhme, Thilo Gross
In adaptive networks fragmentation transitions have been observed in which the network breaks into disconnected components. We present an analytical approach for calculating the tr…
The Casimir spectrum revisited
Carlos A. R. Herdeiro, Marco O. P. Sampaio, Jaime E. Santos
We examine the mathematical and physical significance of the spectral density sigma(w) introduced by Ford in Phys. Rev. D38, 528 (1988), defining the contribution of each frequency…
